Claims
- 1. An optical element comprising:
i) a first polymer matrix; ii) an acrylate-based modifying composition capable of stimulus-induced polymerization wherein said stimulus causes the desired modifications of the element and said changes are produced without subsequent removal of said modifying composition.
- 2. The optical element of claim 1 wherein said modifying composition has the general structure
- 3. The optical element of claim 1.
- 4. The optical element of claim 1 wherein R2 and R3 are both alklys.
- 5. The optical element of claim 1 where R4 is a group capable of photopolymerization.
- 6. The optical element of claim 1 further comprising a photoinitiator.
- 7. The optical element of claim 1 where R4 contains an acrylate or methacrylate moiety.
- 8. The optical element of claim 1 wherein the modifying composition has a molecular weight of from 1000 to 4500.
- 9. An optical element comprising:
i) A first polymer matrix; ii) A modifying composition capable of stimulus induced polymerization said modifying composition being the general formula: 2X—(A)m—Q—(A)m—X1orX—(A)n—(A1)m—Q—(A)m—(A1)n—X1where Q is an acrylate-based multifunctional initiator useful in Atom Transfer Radical polymerization; A and A1 are the same or different and have the general structure 7wherein R is selected from the group consisting of alkyls, halogenerated, alkyls, aryls and halogenerated aryls and R5 is selected from the group consisting of hydrogen, alkyls, aryls, halogenerated aryls, M and N are intergers and X and X1 are the same or different and contains a moiety capable of stimulus induced polymerization.
- 10. The optical element of claim 9 wherein Q is a dehalo acrylate.
- 11. The optical element of claim 10 wherein Q is methyldichloro acrylate.
- 12. The optical element of claim 9 wherein X and X1 contains a photopolymerizable moiety selected from the group consisting of acrylate, allyloxy, cinnamoyl, methacrylate, stibenyl, and vinyl moieties.
